Past and recent climatic changes induced shifts in species ranges. Mantis religiosa has also expanded its range across Germany within the past decades. To determine the ancestry of German M. religiosa we sequenced four mitochondrial genes (COI, COII, Cyt b, ND4) of European M. religiosa populations. We found an east, central and west European lineage of M. religiosa. These distinct lineages are consistent with genetic isolation by distance during glacial periods, and the re-colonization of northern parts of Europe by species from different refugia. Within Germany, we found haplotypes clustering to the central and west European lineage suggesting that M. religiosa immigrated from two directions into Germany. Mismatch distributions, and negative Tajima's D and Fu's Fs values indicate a current range expansion of the central and west European lineage. We hypothesise that ongoing global warming which increases the availability of thermally favourable areas in Germany for M. religiosa adds to its current range expansion. In conclusion, M. religiosa colonized Germany via two directions: west German populations descended from French populations and east German populations from Czech populations.
过去和近期的气候变化导致了物种分布范围的变化。在过去几十年里，欧洲螳螂也在德国扩大了其分布范围。为了确定德国欧洲螳螂的起源，我们对欧洲螳螂种群的四个线粒体基因（细胞色素氧化酶亚基I、细胞色素氧化酶亚基II、细胞色素b、烟酰胺腺嘌呤二核苷酸脱氢酶亚基4）进行了测序。我们发现了欧洲螳螂的一个东部、中部和西部谱系。这些不同的谱系与冰川期期间因距离导致的遗传隔离，以及来自不同避难所的物种对欧洲北部的重新殖民化相一致。在德国境内，我们发现单倍型聚集在中欧和西欧谱系，这表明欧洲螳螂是从两个方向迁入德国的。失配分布以及负的 Tajima's D 和 Fu's Fs 值表明中欧和西欧谱系目前正在扩大其分布范围。我们推测，持续的全球变暖增加了德国对欧洲螳螂来说气候适宜的区域，这促进了其目前的分布范围扩张。总之，欧洲螳螂通过两个方向在德国定殖：德国西部的种群源自法国种群，德国东部的种群源自捷克种群。
